Specification of Letters Patent.

Patented Feb. 12, 1918.

Application led .Tuly 28, 1916. Serial No. 111,808.

To @ZZ fuwm it may concern.'

Be it known that I HENRY A. Hints. a citizen of the United tates, and aresident of the city of Grand Rapids, in the county of Kent and State ofMichigan. have invented certain new and useful Improvements 1n'.Condensers; and I do hereby declare that still, although of coursewell adapted for use in connection with other apparatus wherein acondensing effect is desired.

It is an object therefore of this invention to construct a condenserpresenting a large condensing surface to an entering vapor with thesurfaces so disposed that as the vapor is condensed thereon it flowsrapidly by gravity through the condenser', and with a counter-current ofa cooling medium to maintain said condensing surfaces cool to not onlycondense the vapor but to thoroughly cool the same as it proceedsthrough and leaves the condenser.

It is also an object of this invention to construct a vertical tubecondenser provided with a distributing means at the entrance end thereofto direct the vapor to be condensed so that the same flows through thevarious different tubes, thereby utilizing the full effect of thecondenser to condense the 'apor and cool the condensates as they leavethe condenser.

It is furthermore an object of this invention to construct a condenserembracing an upright cylinder and a plurality of tubes extendingtherethrough and sealed therefrom at the upper and lower ends thereof toadmit a flow of vapor into the upper end of said tubes for condensationtherein, and with -:inlet and outlet means in said c vliuder tointroduce and promote a fiow of cooling liquid around said tubes.

It is finally an object of this invention to construct an improved typeof condenser of large capacity designed to condense and cool a fiuidadmitted thereinto.

The invention (in a preferred form) is illustrated in the drawings andhereinafter more fully described.

In the drawings:

Figure l is a central vertical section with parts in elevation, of acondenser embody- -ing the principles of my invention.

ig. 2 is a section taken on line 2 2 of Fig. 1. V y Fig. 3 is a sectiontaken on line 3 3 of Fig. 1. As shown in the drawings:

The condenser consists of au outer shell 3, lwhich. as shown, is open atits upper end 'and secured therein are a series of upright condensingtubes 15, all communicating at theirvupper ends through an aperturedplate or head 1G. on which there is hrazed, riveted, or otherwisetightly secured thereto a conical hood 17, affording a con'ipartment forthe vapor to be condensed prior to introduction into the condensertubes. The outlet pipe 2, from a still is connected into the upper endof said conical hood 17. Nithin said hood above the plate 1G. is adistributing screen or apertured plate 18, shown as rectangular, andacting to insure an even distribution of the entering fluid to thedifferent condensing tubes 15. by passage through the apertures in saidplate and dispersion over the edges thereof. between which and the wallof the hood, clearance is provided. The lower ends of said condensingtubes 15. are connected through a crown sheet 19. which is rigidlysecured by its fianged periphery to the inner walls of the cylindricalcasing 3, of the condenser by riveting, brazing.' or otherwise.Connected to said cylindrical casing 3. below said crown sheet 19. is aconical bottom afferding a receiving compartment for the condensatesinto which the discharge pipe 1l, is connected. An inlet pipe forcooling water, denoted by the reference numeral 21. is provided, whichcommunicates through the lower end of the cylindrical casing 8, and anoutlet pipe Q2. is connected at the upper end thereof, so that wateradmitted into the condenser completely surrounds the condensing tubesl5, flowing upwardly therearound.

The operation is as follows:

The fluid introduced into the condenser through the pipe 2. forcondensation strikes the distributing plate 18, and is broken up andcaused to spreads in ditferent directions and then passes downwardly forpassage through the condenser tubes 15, so that all ot' said condensertubes are utilized to condense the fluid. The fluid after condensing insaid tubes, flows by gravity downwardly therethrough subjected to thecooling action of the liquid surrounding said tubes, so that as thecondensate flows outwardly from the condenser it is thoroughly cooled. y

I arn aware that various details of construction Inay be varied througha wide range without departing', from the principles of this invention,and l therefore do not purpose limiting the patent granted otherwisethan necessitated by the prior art.

'I claim as I'ny invention:

l. A condenser com risinan outer c liiider open at its upper end, acrown plate in the lower end of the cylinder, a conical bottoni rnernbersecured to the cylinder below the crown plate, a plurality of tubesconnected to the crown plate, an apertured head plate secured to thetubes, a conical hood se cured to the head plate, and a rectangularapertured distributing platerin said hood having spaces around the edgesthereof and the hood. c

2. Acondenser comprising an outer cylinder, tubes therein, a plate inthe bottoni of the cylinder through which the tubes open, a lnernbersecured to the cylinder below the plate, a plate near the top of thecondenser through which the tubes open, a hood secured to the plate, anapertured distributing plate in the hood having a channel between theedge thereof and the hood adapting the uid to be condensed passingthrough the distributing plate and diiiu'sing around the edges thereof,and an inlet and outlet pipe opening into the cylinder.

In testimony' whereof l have hereunto subscribed my `name in thepresence f two subscribing witnesses.
